Abstract
Description
Technical Field
[0001] The utility model relates to a novel measuring tool for the insulating rod of a 220KV grounding wire, belonging to the technical field of power equipment. Background Technique
[0002] When the 220KV equipment is shut down for maintenance, in order to ensure the safety of maintenance personnel, a set of grounding wires need to be hung on the overhead line where power may come back after power outage, and the personnel hold an insulating rod to connect the grounding wire to the overhead line.
[0003] Existing overhead lines are relatively high. When operating personnel hang the grounding wire, they have to stand on an insulating platform to hang the grounding wire. Since the grounding wire is already very heavy, if the center of gravity is unstable when a single person stands on the insulating platform to hang the grounding wire, it is very likely to fall from the insulating platform; and when connecting the grounding wire, the staff needs to fully support the insulating rod with their hands, which increases the intensity of manual labor. Hand soreness is likely to occur after long-term use, and the connection of the grounding wire is not stable enough. Content of the Utility Model
[0004] The purpose of the utility model is to provide a novel measuring tool for the insulating rod of a 220KV grounding wire to solve the problems raised in the above background technique.
[0005] To achieve the above purpose, the utility model provides the following technical solutions:
[0006] A novel measuring tool for the insulating rod of a 220KV grounding wire includes a main support rod, a grounding wire main body and a handle. A sliding inner rod is slidably connected inside the main support rod. The right end of the sliding inner rod is fixedly connected with a fixed rack, and the fixed rack is slidably connected with the main support rod. The right side of the upper end of the main support rod is fixedly connected with a fixed frame. A transmission gear is rotatably connected at the middle position inside the fixed frame, and the transmission gear is meshed with the fixed rack. The upper end of the sliding inner rod is fixedly connected with a wiring support rod, the upper end of the wiring support rod is fixedly connected with a conductive clamping frame, and a lifting clamping block is slidably connected to the upper side inside the wiring support rod. The left end of the conductive clamping frame is electrically connected with the grounding wire main body.
[0007] Further, a turntable is rotatably connected to the right end of the fixed frame. A worm is fixedly connected to the left end of the turntable, and the worm is rotatably connected with the fixed frame. The upper end of the worm is meshed with a worm gear, and the worm gear is fixedly connected with the transmission gear.
[0008] Further, a handle is fixedly connected to the lower end of the main support rod.
[0009] Further, a sliding pull rod is slidably connected to the middle position inside the sliding inner rod. The sliding pull rod is fixedly connected to the lifting clamping block. A spring is covered on the surface of the upper side rod body of the sliding pull rod, and a pull plate is fixedly connected to the lower end of the sliding pull rod.
[0010] Further, limiting sliding grooves are provided on the left side wall of the main support rod and the lower left end of the sliding inner rod.
[0011] Further, the conductive clamping frame is arranged in a C shape, and a circular clamping groove is provided between the conductive clamping frame and the lifting clamping block.
[0012] Further, a strip-shaped groove is provided on the right side inside the main support rod, and the position of the strip-shaped groove corresponds to the position of the fixed rack.
[0013] The beneficial effects of the present utility model are as follows:
[0014] By setting the handle, the staff can hold the device by hand. By rotating the turntable, the worm can drive the worm gear to rotate, so that the transmission gear can drive the fixed rack to move up and down, and then drive the sliding inner rod to move up and down.

This essentially improves the operation safety, reduces the operation time, reduces the number of operators, and improves the operation speed. The present utility model uses the pulling of the pull plate to make the sliding pull rod drive the lifting clamping frame to move downward, so that the conductive clamping frame can be sleeved outside the overhead line, and the set spring can be compressed. After releasing the pull plate, the set spring can stretch, so that the upper end of the lifting clamping block can fit with the conductive clamping frame, and then the conductive end can be limited and sleeved outside the overhead line. Only manual support of the insulating rod is required, reducing the labor intensity of the workers. Description of the Drawings

By rotating the turntable 10, the worm 11 can drive the worm gear 12 to rotate, so that the transmission gear 5 can drive the fixed rack 3 to move up and down, and then drive the sliding inner rod 2 to move up and down. At the same time, by setting the fixed rack 3, the sliding inner rod 2 can be rotationally limited, and then the length of the insulating rod can be adjusted, so that the preparer does not need to prepare an insulating platform, and when hanging the wire, the personnel will not fall from the insulating platform due to unstable center of gravity. This essentially improves the operation safety, reduces the operation time, reduces the number of operators, and improves the operation speed.
[0024] Example 2 Please refer to Figure 1 With Figure 4 , the difference between this embodiment and Embodiment 1 is that: the upper end of the sliding inner rod 2 is fixedly connected to a wiring support rod 6.
